Objectives The craniosacral therapy is closely related to the herbal meridians, so we try to explore, compare and develop pharmacopuncture that can have a synergistic effect. Methods The craniosacral pharmacopuncture, Hominis placenta pharmacopuncture, jungseongohhyeol pharmacopuncture, bamboo salt pharmacopuncture 1.8%, bamboo salt pharmacopuncture 3.0%, and normal saline, which are used with craniosacral therapy in clinical practice, were all made and prepared by ourselves. In order to compare antioxidant activity, 2,2-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid), 2,2-diphenyl-1-picrylhydrazyl, ferric reducing antioxidant powder, total flavonoids, total phenolics methods were all measured. Method validation such as specificity, linearity, precision, and accuracy were performed for craniosacral pharmacopuncture. Results In all antioxidant methods, craniosacral pharmacopuncture showed the highest activity and followed by a Hominis placenta pharmacopuncture. The rest of the pharmacopunctures were measured to have low antioxidant activity. Nodakenin and glycyrrhizin were suitable as index compounds of craniosacral pharmacopuncture and they contained 0.82±0.01 ㎍/mL and 2.56±0.01 ㎍/mL respectively. Conclusions Craniosacral pharmacopuncture has the highest activity in all antioxidant activity experiments, which will help activate craniosacral therapy and quality control is possible through standardized research. Such research will contribute to the development of the oriental medicine industry.

This study was carried out to investigate the quality characteristics and antioxidant activities of Rehmanniae radix (Rehmannia glutinosa Libosch. var. purpurea Makino) freeze-dried powder (RRP) and Rehmanniae radix preparata powder (RRPP). Under the Hunter color system, redness was higher and lightness/yellowness lower in RRPP, compared to RRP. The reducing sugar contents of RRP and RRPP were 0.8% and 6.0%, respectively (p<0.05). The pH was lower in the RRPP (RRP: 6.71, RRPP: 4.23). The amount of catalpol amount in RRPP (47.20 mg/mL) was lower than RRP (144.90 mg/mL). RRPP contained high amounts of 5-HMF (5-hydroxymethyl-2-furaldehyde, 47,231 mg/mL), but 5-HMF was not detected in RRP. Total phenol contents of RRP and RRPP were 2.10 mg/mL and 3.66 mg/mL, respectively. FRAP values of RRP and RRPP were 0.51 mg/mL and 1.99 mg/mL, respectively. The antioxidant activities by DPPH (1,1-diphenyl-2-picryl hydrazyl) and hydroxyl radical scavenging activity of RRPP were much higher than RRP. Based on these results, RRPP is a good candidate for food processing in terms for its physicochemical and antioxidative activities.

This study aimed to determine the effects of freeze-dried onion powder (OP) which contains rich in quercetin (22 mg/10 g) on hyperlipidemic participants. Fourteen participants (total cholesterol level in plasma $270.8{\pm}21.4mg/dL$) $40{\sim}59$ years of age who were diagnosed as hyperlipidemia by a physician at Fatima Hospital in Changwon took part in this study for 12 weeks. We investigated the anthropometric data and dietary habit by using questionnaires. Also, blood samples were collected from the patients in fasting before and after this 12 weeks intervention study. 78.6% of the patients showed interest in health diet management and weight control; however, they also showed some problems in their dietary habit (meal irregularity, food choice, calorie nutrient balance, high fat and cholesterol etc.) and life style (smoking, eating out, alcohol intake) that could have adverse effect on hyperlipidemic therapy. Most participants (85.7%) thought that OP was good for their health. The total cholesterol and LDL-cholesterol significantly decreased with OP intake. The HDL-cholesterol increased and the Atherogenic index (AI) significantly decreased. Regarding the correlations of dietary habit and life style with anthropometric and biochemical factors, the alcohol intake level was significantly correlated with the frequency of eating out and body mass index (BMI). Exercise level showed positive correlation with HDL-cholesterol and negative correlation with atherogenic index (AI). These results suggest that the intake of polyphenol rich onion may decrease the risk of hyperlipidemia by reducing cholesterol level. We consider these hypolipidemic effects of OP as a possible functional food. However, further research such as a well designed longterm clinical study with experimental and placebo groups is needed.

Antioxidative capacities of Stachys sieboldii MIQ and 6-year-old ginseng powder were assessed after extraction with 80% ethanol, and their addition effects on quality characteristics of cookies were determined. Stachys sieboldii MIQ showed 3.12-fold higher total phenol content (TPC) and higher antioxidative capacities than ginseng based on higher values of 2,2-diphenyl-1-picrylhydrazyl radical scavenging capacity, ferric reducing antioxidant capacity, and Trolox equivalent antioxidant capacity (P<0.05). The 80% ethanol extract was then fractionated with $H_2O$ (Fr. I), 30% (II), 50% (III), 70% (IV), and 100% ethanol (V). Fractions of Stachys sieboldii MIQ extract showed 2.2-fold (Fr. I)~6.1-fold (III) higher TPC and higher antioxidative capacities than ginseng extract fractions. TPC was in the order of fractions III> II> I> IV> V for Stachys sieboldii MIQ extract while in the order of fractions I~III> IV~V for ginseng extract, assuming that Stachys sieboldii MIQ contained more phenolic compounds with higher polarity than ginseng. Addition of 5% and 10% Stachys sieboldii MIQ and ginseng powder increased spread ratio in cookies compared to 100% wheat flour, and 10% addition of Stachys sieboldii MIQ resulted in the darkest and most reddish cookies. In the sensory evaluation, cookies with 5% and 10% Stachys sieboldii MIQ received higher scores for taste preference and higher overall acceptability than ginseng or control cookies. Therefore, powder of Stachys sieboldii MIQ could impart more favorable sensory characteristics as well as higher antioxidative capacity than ginseng in bakery products.

Cementation and solvent extraction processes were studied to separate nickel and iron ions from the $H_2SO_4$ leaching solution with 47 g/L $Fe(Fe^{2+}/Fe^{3+}=1.03),$, 23.5 g/L Ni and 0.90M $H_2SO_4$ which leached from Fe-Ni alloy. Iron powder was used as a reducing agent for the cementation of Ni ion from the leaching solution. The reduction percentage of Ni ion was $17{\sim}20%$ by adding 4 times stoichiometric amount of iron powder at $60{\sim}80$. This may result from the fact that the cementation of Ni ion occurred after the reduction of $Fe^{3+}$ to $Fe^{2+}$ and the neutralization of $H_2SO_4$ with iron powder. The cementation process was proved to be unfeasible for the separation/recovery of Ni ion from the leaching solution including $Fe^{3+}$ as a major component. $Fe^{2+}$ present in the leaching solution was converted to $Fe^{3+}$ for solvent extraction of Fe ion using D2EHPA in kerosene as a extractant. The oxidation of $Fe^{2+}$ to $Fe^{3+}$ was completed by the addition of 1.2 times stoichiometric amount of 35% $H_2SO_4$. 99.6% $Fe^{3+}$ was extracted from the leaching solution (23.5 g/L $Fe^{3+}$) by 4 stages cross-current extraction using 20 vol.% D2EHPA in kerosene. $NiSO_4$ solution with 98.5% purity was recovered from the $H_2SO_4$ leaching solution of scrapped Fe-Ni alloy.

Instant face lifting cosmetics contain various film forming agents for stretching the wrinkles on the skin surface. But, most of the film-forming polymers have sticky feels. And they are easily scrubbed out when skin is rubbed on. In this study, we focused on the influence of sodium silicate that has rapid film forming effect on skin surface and immediate wrinkle reducing effect. Sodium silicate, also known as water glass or soluble glass, is a compound containing sodium oxide and silica. Sodium silicate is a white powder that is readily soluble in water, producing an alkaline solution. Sodium silicate is stable in neutral and alkaline solutions. The sodium silicate solution hardens by drying in air and rapidly forms a thin film. When the solution is applied to the skin, the fine membrane coating is formed by water evaporation and ionic bond re-formation. It also makes the strong siloxane (Si-O) bonding on the skin surface. When these fixation properties are applied to cosmetics, they can give remarkable skin tightening effect. The sodium silicate solution can provide the lifting effect by forming a film on skin at a proper concentration. But, skin irritation may be caused with too high concentration of sodium silicate. We studied a desirable range of the sodium silicate concentration and combination with other fixatives for skin care formulation that has no sticky feels and no scrubbing out phenomenon. Immediate lifting gel was developed by using sodium silicate and various thickening systems. Among of the various thickeners, aluminum magnesium silicate showed the best compatibility with sodium silicate for rapid lifting effect. This instant physical lifting gel was confirmed as a low stimulating formula by skin clinical test.

Recently interests on raw-food diets are rapidly increasing in relation to chronic diseases prevention in Korea, but studies on raw-food diets have been hardly performed by nutritionists. This study was performed to investigate the effects of low-calorie diets using a raw-food formula in the form of freeze-dried powder on obesity and its complications in the obese women (body mass index (BMI) $\geq$ 25kg/㎡) for eight weeks. Forty premenopausal women (mean BMI 28.04kg/㎡, mean age 28.33years old) participated in this diet intervention, and were controlled by eating 1 regular meal, 1-2 snacks and 2 raw-food formula (140kcal/pack) meals a day within the 1500-1300kcal ranges. Anthropo-mentric measurements, body compositions, physical exercise, and obesity-related risk factors were assessed before (the initial), during (the 4th week) and after (the 8th week) the study. All the data was analyzed by paired t-test, repeated measures ANOVA, and nonparametric rank test at p<0.05 level. Obesity was significantly increased during this study, and it was decreased in weight (-4.59%, p<0.000), BMI (-4.56%, p<0.000), body fat percent (-6.18%, p<0.000), fat mass (-10.19%, p<0.000), waist and hip circumferences(-5.69%, p<0.000 and -2.55%, p<0.000) and WHR (-3.24%, p<0.000). Energy expenditure of physical exercise was increased as much as 70kca1/day during the study (p=0.000), but it did not have any correlations with weight loss and changes of body compositions. Biochemical measurements including blood triglyceride(p <0.006) and leptin(p<0.000) levels were significantly decreased, LDL cholesterol level was increased(p<0.05), but all the blood lipid levels were in the normal ranges. Fatty liver echogenicity and menstrual irregularity were improved after the diet intervention(p<0.000 and p<0.034). In conclusion, this B-week low-calorie diet intervention using raw-food formula was effective for obese premenopausal women in reducing obesity and its risk factors so as not to proceed towards comorbidities. However, the variation of blood lipid levels should be observed for a longer Period.

This study was conducted to investigate the anti-oxidative abilities of certain products in Ulleungdo, such as sweet pumpkin (Danhobak), goat's beard (Samnamul), and Aster glegni (Bugigangyi), quality characteristics of sweet pumpkin taffy containing these products. Total polyphenolic contents of the Samnamul water and ethanol extracts were 2.95 mg% and 3.57 mg%, respectively, whereas those of the Bugigangyi water and ethanol extracts were 2.77 mg% and 2.75 mg, respectively. However, the total polyphenolic contents of the pumpkin water and ethanol extracts were 0.32 mg%. Reducing power ($OD_{700}$) of the Samnamul and Bugigangyi water and ethanol extracts (0.01%, w/v) was in the range of 1.62~1.91, which was higher compared to those of sweet pumpkin (0.02~0.03). Electron donating abilities (EDA) of the 0.01% Samnamul and Bugigangyi water and ethanol extracts were in the range of 74.91~79.21%, whereas those of the sweet pumpkin water and ethanol extracts were 3.79~14.99%. Optimum mixing ratio of steamed sweet pumpkin and water taffy for the preparation of taffy was 25:75 (w/w), as evaluated by sensory evaluation. Optimum adding ratio of Samanmul and Bugigangyi ethanol extracts to pumpkin taffy were 0.4% and 3%, respectively. However, the adding ratios of Samanmul and Bugigangyi powder to pumpkin taffy were 0.5~1.0% (w/w) and 1% (w/w), respectively.

"Hae-Songi" mushroom is a kind of Hypsizigus marmoreus, one of the edible mushrooms. Powder and hot water extracts of the mushroom fruit-body were investigated for their proximate composition, amino acid contents, ${\beta}-glucan$ contents, total phenolic contents and antioxidant activity. The measured antioxidant activity included free radical scavenging activity against DPPH, reducing power $Fe^{2+}$ chelating ability and SOD activity. Mushroom extracts exhibited in vitro antioxidant activity. This mushroom contained high protein (29%, total amino acid contents 204.86 mg/g), free amino acids (46.53 mg/g) and ${\beta}-glucan$(0.11%). At a concentration of 1% extracts solutions (w/v) according to different extraction times, DPPH free radical-scavenging activities were found to exhibit $89%{\sim}92%$ inhibition. Positive correlations $(R^2=0.9901{\sim}0.7424)$ were found between total phenolic content in the mushroom hot water extracts and their antioxidant activity. In this study, it is demonstrated that "Hae-Songi" mushroom may possess potential for use as a health food, due to theirantioxidant capacity.
